Large Genetic Study Identifies 42 DNA Variants Linked to Dyslexia; Possible Link with Ambidexterity Revealed

Scientists have, for the first time, pinpointed a large number of genes that are reliably associated with dyslexia. Approximately one third of the 42 genetic variants identified have been previously linked to general cognitive ability and educational attainment. The researchers say their findings, published online on October 20, 2022 in Nature Genetics, aid our understanding of the biology behind why some children struggle to read and/or spell. The open-access article is titled “Discovery of 42 Genome-Wide Significant Loci Associated with Dyslexia.”
